Abstract
A dynamic demonstration model for human ear sound hearing relates to a teaching aid, and employs a thin plastic bowl as an auricle. A plastic film covered on a bowl opening of the thin plastic bowl serves as an eardrum of a simulated ear; a plastic tube is connected with a circular hole at the bottom of the thin plastic bowl; a pin is connected onto the plastic tube; a conducting line is connected onto the pin; the other end of the conducting line is connected with the center position of the plastic film covered on the bowl opening of the thin plastic bowl; a screw is arranged at the contact position of the conducting line of a light-emitting diode and the pin; a teacher adjusts the distance between the screw and the pin, and claps towards the plastic bowl opening until the light-emitting diode emits light; and then a dynamic simulated experiment of human ear sound hearing is realized. The dynamic demonstration model for human ear sound hearing has the advantages of being capable of enabling students to analyze the transfer process of sound inside an ear, gradually recognizing the function of each portion of the human ear, tremendously arousing the learning interest of the students and making a deep learning impression.
Description
Technical field
The utility model relates to a kind of teaching aid.
Background technology
In existing teaching aid instrument, do not have also that a teaching aid can listen people's ear the process of sound directly perceived, image, dynamically demonstration is come out.Existing people's ear model also can only allow its structure of students ' understanding, the process of can't demonstrating sound transmitting.
Summary of the invention
The purpose of this utility model is to provide a kind of people's ear to listen dynamic demonstrating model, it is with a thin plastic bowl body that this people's ear is listened dynamic demonstrating model, bottom at thin plastic bowl body cuts a circular hole, on the rim of a bowl of thin plastic bowl body, cover with layer of plastic film, as the eardrum of simulation ear; Be connected on the circular hole that thin plastic bowl body cuts with a plastic tube, thin plastic bowl body as auricle, plastic tube as external auditory meatus; Then this device is fixed on the portrait that is printed on ear and human brain structure.Connect a pin on plastic tube, connect a lead on the pin, the center of the plastic sheeting that covers on the rim of a bowl of the other end of lead and thin plastic bowl body is connected; Establish a screw at the lead of light emitting diode and the place, contact of pin; Then this device is fixed on the relative position of corresponding cochlea and phonophore; By screw and lead simulation cochlea, the auditory nerve that the sound wave of receiving is simulated by lead is passed to the auditory center of human brain, fixes a light emitting diode and simulate auditory center on the position of the auditory center of human brain structure portrait; With electric wire the lead on light emitting diode, the screw, lead on the pin and dry cell are together in series at last and can realize that people's ear listens the dynamic simulation experiment of sound.
During use, the distance between set screw and the pin needle point is aimed at the plastic bowl body then and is clapped one's hands, and causes the plastic sheeting vibration, can connect circuit, makes lumination of light emitting diode.Clap the hands by aiming at plastic bowl body auricle, make the lumination of light emitting diode that places brain, illustrate that acoustic signals has been communicated to brain.Thus, can allow the transmittance process of students ' analysis sound in ear, progressively be familiar with the effect of people's ear each several part.Because the student can participate in research in person, thereby can greatly motivate students' interest in learning, and stays deep study impression.
People's ear listen dynamic demonstrating model be with a thin plastic bowl body as auricle, play the effect of collecting sound wave; Bottom at thin plastic bowl body cuts a circular hole, covers with the eardrum of layer of plastic film as the simulation ear on the rim of a bowl of thin plastic bowl body, and eardrum has the effect that causes vibration; Be connected on the circular hole that thin plastic bowl body bottom cuts as external auditory meatus with a plastic tube, external auditory meatus has the effect of conducted acoustic waves; This device is fixed on the portrait that is printed on ear and human brain structure, then to show simulate live; Connect a pin on plastic tube, connect a lead on the pin, the center of the plastic sheeting that covers on the rim of a bowl of the other end of lead and thin plastic bowl body is connected, and pin and lead are simulated phonophore can pass to cochlea to vibration; Establish a screw at the lead of light emitting diode and the place, contact of pin, by screw and lead simulation cochlea and auditory nerve, the sound wave of receiving is passed to the auditory center of human brain by the auditory nerve of lead simulation, on the position of the auditory center of human brain structure portrait, fix a light emitting diode and simulate auditory center; With electric wire the lead on light emitting diode, the screw, lead on the pin and dry cell are together in series at last and can realize that people's ear listens the dynamic simulation experiment of sound.
Adopting people's ear to listen the beneficial effect of dynamic demonstrating model is to allow the transmittance process of students ' analysis sound in ear, progressively is familiar with the effect of people's ear each several part.Because the student can participate in research in person, thereby can greatly motivate students' interest in learning, and stays deep study impression.
Description of drawings
Fig. 1 is the structural representation that people's ear is listened dynamic demonstrating model.
Embodiment
With reference to Fig. 1, people's ear listen dynamic demonstrating model be with a thin plastic bowl body 1 as auricle, play the effect of collecting sound wave; Bottom at thin plastic bowl body 1 cuts a circular hole, covers with the eardrum of layer of plastic film 2 as the simulation ear on the rim of a bowl of thin plastic bowl body 1, and eardrum has the effect that causes vibration;
Be connected on the circular hole that thin plastic bowl body 1 cuts as external auditory meatus with a plastic tube 3, external auditory meatus has the effect of conducted acoustic waves; This device is fixed on the portrait that is printed on ear and human brain structure, then to show simulate live;
Connect a pin 5 on plastic tube 3, connect a lead 4 on the pin 5, the center of the plastic sheeting 2 that covers on the rim of a bowl of the other end of lead 4 and thin plastic bowl body 1 is connected, and pin 5 is simulated phonophores with lead 4 can pass to cochlea to vibration; Establishing a screw 6 at the lead of light emitting diode and the place, contact of pin, connecting a lead 7 on the screw 6 can be connected with a light emitting diode 8; By screw 6 simulation cochlea, the auditory nerve that the sound wave of receiving is simulated by lead 7 is passed to the auditory center of human brain, fixes a light emitting diode 8 and simulate auditory center on the position of the auditory center of human brain structure portrait; With electric wire the lead on light emitting diode, the screw, lead on the pin and dry cell are together in series at last and can realize that people's ear listens the dynamic simulation experiment of sound.
